Answer:
A) Height › 48
Step-by-step explanation:
the height of a person must be greater than 48 in.
We know that
if <span>|x+ y-7|+ |4x - y+ 12|= 0
then
</span>x+ y-7=0
and
4x - y+ 12=0
using a graph tool
see the attached figure
the solution is the point (-1,8)
the answer is<span>
the ordered pair of real numbers is (-1,8)</span>

Answer:
B) y = 0.25x +5
Step-by-step explanation:
The x-value differ by 1, so the slope is the difference in y-values.
Comparing for x=2 and x=3, we see that the y-value increases by 0.25 from 0 to 0.25. This is the slope of the data in the table.
The equation with the same slope will have 0.25 as the x-coefficient. The equation of choice B is the one you're looking for.
y = 0.25x +5
_____
You don't care about the equation of the table, but it is ...
y = 0.25x -0.5
